the (French?) reaction stated:
error during writing of /boot/System.map-4.13.0-36-generic.dpkg-new; no space left on disk.

There are 2 main possibilities:
.1. the BOOT- or the ROOT- partition is too small
and thus is completely filled up during an update

.2. on the BOOT- or the ROOT- partition there is a lot of "old info"
and thus completely filled up during the update

# -- the updating of programs is done with special rights (the so called root-user)
Under this user one can use the entire disk; so fill it up to 100%
As a "normal" user you may not fill it up to 100%

First we must know what the situation is now. We need to enter a Terminal-command to do so.
I try to explain in simple words how to do it.

* open a text editor (e.g. Mousepad, LibreOffice, AbiWord) and leave it opened
Minimalize this window using the - in the upper corner right above (MINUS sign near + and x)
* start a terminal window (e.g. menu Application-Menu >> All >> Terminal OR Application-Menu >> Accesoires >> Terminal) I do not know the French Menu-names...

In this terminal window, enter the next line (linux-command) completely, followed by the <Enter-Key> (sometimes called <Return-Key> on your keyboard) :
df --si

This command will give some lines info about the partitions on your PC.
* with the mouse, select ALL info given by this command
EITHER right-mouse-key select " Copy "
OR in the menu-bar select " Edit " >> " Copy "

* now select the editor you have opened before (Mousepad / LibreOffice / AbiWord / ... )
there click in the white space of a new document and select " Paste "
The info is now in this document (not yet saved)

Go back to the terminal-window,
click with your mouse somewhere below the text.

To close this window, enter the next command (followed by the <Enter-Key>)
exit
You will see this window close.
